Dr. Ralf Kleef is a well-known and acclaimed medical and naturopathic doctor specialized in Immunotherapy & Hyperthermia for patients with neoplastic & other chronic illnesses. With his training in immunology in Germany and at Memorial Sloan Kettering Cancer Centre in NYC and later at the NIH, Office of Alternative Medicine (OAM), in 1996 he found his passion: treating cancer through immunotherapy in the footsteps of the father of cancer immunotherapy, William B. Coley.
He founded his Insitute for Hyperthermia and Immunotherapy 1998 in Vienna and treated more than 20,000 patients over the last three decades. His journey goes on with expanding his center to Budapest, Hungary.
Dr. Kleef invented a unique cancer treatment concept: immunotherapy combined with hyperthermia and complementary medicine in an integrative approach which is personalized for each and every patient to support the patient´s immune system to fight the illness.
We believe that this is a safe protocol, which is easily tolerable for patients. In our treatments, the side effects of immunotherapy (immune-related adverse effects) occur in much lesser degrees of intensity. Perfecting his approach over the last years, he was able to improve the effectiveness of treatment to a considerable extent.
